My invention relates to improvements 1n hand oilers, and moreparticularly to pumpactuated hand oilers having nozzle-equipped deliveryspouts.

b To the above end, generally stated, the in vention consists of thenovel devices and combinations of devices hereinafter descrlbed anddefined in the claims.

In the accompanying drawings, which .1l-

l lustrate the invention, like characters 1ndicate like parts throughoutthe several views.

Referring to the drawings:

Fig. 1 is a view principally in elevation showing one form of theinvention;

F ig. 2 is a View principally in section, taken centrally through Fig.1, on the axis of the pump;

Fig. 3 is a view corresponding to Fig. 1

but showing another form of the improved oiler; and

Fig. 4 is a view corresponding to Fig. 2, but taken centrally throughthe oiler shown in Fig. 3. y

Referring first to the invention as illustrated in Figs. 1 and 2, thenumeral 5 indicates a cast oil receptacle havinga removable castdome-like cover 6 detachably secured thereto by screw threads 7. Thereceptacle 5 and its cover 6 are provided with knurled circumferentiallyextended bandlike raised surfaces`8 and 9, respectively, by which saidreceptacle and cover may be held when screwing said cover into thereceptacle or removing the same therefrom.

Y The oiler is provided with a C-shaped handle 10 attached to thereceptacle 5 by means of upper and lower transversely divided clampingrings 11. The ends of the handle 10 extend between the ends oftheclamping rings 11 and are secured thereto by means of draws bolts 12inserted through aligned eyes in said ends, and which bolts hold theclamping'rings 11 frictionally contracted onto the receptacle 5. Thelower clamping ring 1l is mounted in a circumferentially eX- tendedgroove 13, formed i-n a raised band .14 on the receptacle 5, and holdsthe handle 10 in its proper position in respect to said receptacle.Formed in the cover 6 near the top thereof is a filling opening15through which oil x may be poured into the receptacle 5, and whichfilling opening is normally closed by a screw plug 16 having a knurledhead and an air vent 17. AA gasket 16 is interposed between the cover 6and the head of the screw plug 16.

A straight upright coupling 18 having an aXial passageway is securedinto a bossed opening 19 in the cover 6, and a gasket 2() is interposedbetween said cover and a shoulder on said coupling. The lower end of anupright spout 21 is'screwed into the upper or outer end of the coupling18, and which spout and coupling have knurled circumferentially extendedsurfaces 22 and 23, respectively, by which they may be held while beingturned. A detachable, adjustable nozzle 241, having a knurled surface,is screwthreaded into the upper end of the spout 21. Obviously, byturning the spout 21 in respect to the coupling 18 or by turning thenozzle 24 in respect to said spout, the direction in which oil may bedischarged from said nozzle may be varied, at will, while holding theoiler by its handle 10.

Within the receptacle 5 and Cover 6 is a depending casing 25 having anintermediate oil. intake chamber 26. The upper end of the casing 25 isscrewed onto the lower or inner end of the coupling 18 and has in itsupper end portion a valve chamber 27. A depending intake pipe 28 has itsupper end screwed into the lower end of the casing 25 with its lower endterminating close to the bottom of the receptacle 5 and having in itsupper end a valve chamber 29. A gasket 30 is interposed between theunder side of the cover 6 and the upper end of the casing 25 to form atight joint between the coupling 18 and said casing. To form a tightjoint between the lower end of the casing 25 and the intake pipe 28,there is interposed between said two members a gasket 31.

The intake pipe`28 opens into the valve chamber 29 and a port 32connects said chamber to the oil intake chamber 26, and a port33connects said chamber26 to the Vvalve chamber 27 which in turn isconnected to the spout 21 by the coupling 18. The intake pipe 28 isnormally closed by a spring held check valve 34l in the valve chamber 29.to prevent af return iow of oil from said chamber to the receptacle 5through the intake pipe 28.V This check valve 34 is mounted in thevalvev chamber 29 and rests on a seat 35 formed in the upper end of theintake pipe 28. A check valve 36, mounted in the valve chamber 27 andresting on a. seat 37 formed with the upper end of the port 33, normallycloses said port to prevent a return flow of oil `from the valve chamber27 to the valve intake chamber 26.

A cylinder 38, of a cylinder and piston pump, extends radially into thecover 6 in a slightly inclined position and is in the same plane withthe handle 10. rlhis ,cylinder 38 is loosely telescoped through a sleeve39 which is formed with the cover 6 and extends both inside and eutsidethereof, and the inner end oi said cylinder has screw-threadedengagement with the casing 25 and opens into the oil intake chamber 26.Telescoped on the outer end of the pump cylinder 38 is a head 40 havingscrewthreaded engagement with the sleeve 39. Mounted in the pumpcylinder 3S is a piston 4l to which the inner end et a piston rod 42 isattached, and which rod works through an axial opening in the head 40.On the outer end of the piston rod 42 is a thumb piece 43 and a spring44 is compressed between an internal shoulder in the pump cylinder 36and the inner end oit the piston 41 and holds said piston in the outerend of the pump cylinder 38 with its rod 42 projected. A gasket c45 isinterposed between the casing and a shoulder on the inner end portionoil' the pump cylinder 38 to Jform a tight joint between the intakechamber 26 and interior of the receptacle 5. rlhe thumb piece 43 islocated directly over the handle l0 so that a persen holding the oilerby said handle may engage the thumb piece with his thumb and depress thesame against the tension of the spring 44.

The suction or intake stroke of the piston 41 lills the'oil chamber' 26with the oil from the receptacle 5 and is produced by the spring 44, andat which time the check valve 34 opens and the check valve 36 remainsclosed. Ilhe compression or discharge stroke of the pump is produced bydepressing the thumb piece 43 to move the piston 4l against the tensionof the spring 44 and thereby force the oil in the intake chamber 26through the spout 2l and discharge the same from the nozzle 24, andduring this stroke ot the piston, the check valve 34 remains closed andthe check valve 36 opens. Upon releasing the thumb piece 43, the spring44 will again return the piston 4l to normal position and again producea suction stroke to refill the oil intake chamv ber 26 from thereceptacle 5.

0bviously, by unscrewing the cover 6 from the receptacle 5, access maybe had to the interior of said cover and receptacle for the purpose ofcleaning the same or making any repairs or adjustments. Aside from thereceptacle 5 and its handle, all ofthe parts of the oiler are carried bythe cover 6. rl`he various parts of the oiler are closely litted Vwithtight joints therebetween, and the action of the valves 34 and 36 aswell as the cylinder and piston pump are very positive in their action,and if desired oil may be discharged from the receptacle 5 withconsiderable force and thrown a considerable distance. By turning eitherthe spout 2l or its nozzle 24, oil, as previously stated, may bedischarged in any desired direction, thus making it extremely easy tooil parts of machines or fill oil cups that are diicult t0 reach orlocated in inaccessible places.

Referring now to the invention as shown in Figs. 3 and 4, the numeral 46indicates a cast oil receptacle having a removable dome-like cover 47detachably secured thereto by screw-threads 48 and having a gasket 49interposed therebetween. rlhe receptacle 46 and its cover 47 areprovided with knurled circumferentially extended bandlike raisedsurfaces 50 and 5l, respectively, by which said receptacle and cover maybe held when screwing said cover onto said receptacle or removing thesame therefrom.

ln the cover 47 is a filling opening 52 normally closed by a screw plug53 having a knurled head, and through which opening oil y may be pouredto lill the receptacle 46. A gasket 54 is interposed between the cover47 and head of the screw plug 53, and an axial bore in said screw plugailords an air vent Extending upward from the top of the cover 47 is ascrew-threaded nipple 56. A substantially pf3-shaped handle 57 has itsupper end portion bent horizontally over the cover 47 and provided witha large eye through which the nipple 56 projects and connects saidhandle to the cover 47. The lower end of the handle 57 is secured to thereceptacle 46 by means of a transversely divided clamping band 58, theends of which embrace the lower end of the handle 57 and are securedthereto by means of a draw bolt 59 inserted through aligned eyes in saidhandle andk ends of the clamping band 58. V

A coupling 60 is loosely telescoped into the cover 47 through the nipple56 and is provided with an intermediate collar 61 which extends over thenipple 56V and is secured thereto by means of a union 62. A gasket 63 isinterposed between the nipple 56 and collar 6l. intake tube 64 has itsupper end portion telescoped into the lower end portion of the coupling60 and is secured thereto by means of a packing nut 65. rllhe lower endof the oil intake tube 64 is locatedrjust above the bottom of thereceptacle 46. lnV the upper end portion of the coupling 60 is a valvechamber 66, in the bottom of which is a valve seat 67 normally closed bya ball valve` 68 yieldingly held closed by a spring 69.

A casing 70 has its lower end portion crewed onto the end of thecoupling 60, and which casing is provided with an inter- The upper endof an oil Y mediate oil intake chamber 71, and in the chamber 72. A port73 connects the oil intake chamber- 7l with the valve chamber 72 and hasin its upper end a valve seat 74 on which rests a ball valve 75yieldingly` held closed by a spring 76. rlhe lower end of a spout 77 isscrewed into the upper end of the casing 70 and a packing 78 isinterposed therebetween. The upper end of the spout 77 is provided witha laterally curved nozzle 79, and which spout, near its lower endportion, is provided with a knurled circumferentially extended surface80 by which said spout may be turned in the coupling 60 to position itsnozzle 79 in any desired rotated position in respect to the oiler.

A horizontal radially disposed pump cylinder 8l, located directly overthe handle 57, is screwed into a bossed Opening in the casing 70 withits inner end opening into the oil delivery chamber 7l, and whichcylinder has a knurled head 82 applied to its outer end by means ofscrew threads. Mounted in the pump cylinder 8l is a piston 83 secured toa piston rod 84 working through an aperture in the cylinder head 82 andhaving on its outer end a thumb piecel A spring 86 is compressed betweenthe well of the chamber 7l and piston 83 and normally holds said pistonin the outer end of the pump cylinder 8l, and when said piston is movedto produce a compression stroke said spring returns the same to normalposition and produces the suction stroke thereof. A gasket 87 isinterposed between the casing 7 O and the collar on the pump cylinder81.

The action of the oiler just described is the same as that of the oilerillustrated in Figs. l and 2 and the check valves 68 and 75 are arrangedto operate in the same manner that the check valves 34 and 36 operate:

That I claim is:
